A Threshold Key Management Scheme for Mobile Ad Hoc Networks Using Elliptic Curve Dlog-Based Cryptosystem

Self Cite

In mobile ad hoc networks (MANETs), traditional security solutions are not adequate due to the infrastructureless nature and the absence of centralized administration. In this paper, a threshold key management scheme for MANETs is presented. The proposed scheme is implemented using elliptic curve dlog-based cryptosystem. In this scheme, an off-line central authority (CA) is required in the initialization phase before network deployment. The CA creates and preloads the shares matrix for each mobile node in the network initialization phase. Each session member generates its private/public key pair, and the session public key by collaborating with its trusted neighbors. The generation of the node private/public key pair, and the session public key is performed without any prior communication between session members. The advantages of the proposed scheme are justified through extensive timing and network simulations

“…Despite this, there are rich literatures on public key management in MANETs (see Refs [12][13][14][15][16][17] for example). This approach can cause both unfavorable communication latency and often tremendous communication overhead, which are also the drawbacks of self-organized key management schemes [18,19]. (2) ID-based cryptography for MANETs has been gaining momentum in recent years [2][3][4]8].…”

Virtual private key generator based escrow‐free certificateless public key cryptosystem for mobile ad hoc networks

2012

A certificateless public key cryptosystem can make a special contribution to building key distribution and management architecture in resource‐constrained mobile ad hoc networks (MANETs) because it has no separate certificate and no complex certificate management problems. In this paper, we present a virtual private key generator (VPKG)‐based escrow‐free certificateless public key cryptosystem as a novel combination of certificateless and threshold cryptography. Using secret sharing, we build a VPKG whose members collaboratively calculate the partial private key and send it to the user via public channels. The private key of a user is generated jointly by the VPKG and the user. Each of them has “half” of the secret information about the private key of the user. In addition, binding a user's public key with its identity and partial private key, respectively, raises our schemes to the same trust level as is enjoyed in a traditional public key infrastructure. We also show that the proposed scheme is secure against public key replacement attacks and passive attacks. Copyright © 2012 John Wiley & Sons, Ltd.

“…Key management is defined as a set of procedures to support the cryptographic algorithm , including initial parameters, key pairs, and secret values. Usually, a key management scheme in MANETs only provides one type of key management method, such as threshold key management scheme , group key management scheme , autonomous key management scheme , identity (ID)‐based key management scheme , and key pre‐distribution management scheme . In , ID‐based and threshold cryptography are combined to give a certificateless solution in MANET.…”

In order to resolve the problems of node multiple keys management and protected storage in mobile ad hoc networks, a new identity‐based node key management scheme combined with next generation protected storage of portable trusted platform module was presented for mobile ad hoc networks. In the scheme, the combined public key based on elliptic‐curve cryptography was adopted to generate multiple keys, which were protected and managed by the next generation protected storage of portable trusted platform module. We show that our scheme is semantically secure under the elliptic‐curve DDH assumption. Also, performance evaluation of proposed scheme in a real‐world ad hoc network indicates the feasibility in practice. Copyright © 2015 John Wiley & Sons, Ltd.
